coMPoUND TOOL.

Application led February 29, 1928. Serial No. 257,998.

This invention provides a composite tool which is readily adapted for a variety of uses generally requiring the provision of a number of individualtools, thereby economizing space, cost and time, since the several tools are ready at hand for immediate use when required.

l/Vhile the drawings illustrate a preferred embodiment of vthe invention it is to be undei-stood that in adapting the means to meet specific needs and requirements the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is t0 be had to the following description and the drawings hereto attached in which,-

Figure 1 is a side view of a compound tool embodying the invention, the compass and the saw being extended.

Figure 2 is a view similar to Figure lshowing the compass and saw in withdrawn or folded position and the tool adapted forstoring. v

Figure 3 is an enlarged sectionalviewuon the line 3-3 of Figure 2.

Figure 4 is an enlarged detail sectional view on the line 4-1 of Figure 1.

Figure 5 is an enlarged sectional view on the line 5-5 of Figure 1.

Figure 6 is a detail sectional view on the line 6-6 of Figure 2, showing the parts on a larger scale.

Figure 7 is an enlarged detail view of a portion of the tool, as seen from the back.

Figure 8 is a detail sectional view of the longitudinal portion of the frame showing a modification admitting of the saw blade entering edgewise into the groove.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The tool includes a frame whichis substantially of U-form and comprises a. longitudinal member 10 and end members 11. The back of the frame is grooved, as indicated at 12 to receive and house a saw blade 13. The groove 12 may be wide to'receive the saw blade 13 flatwise, as indicated most clearly in Figure 3 of the drawings. As

indicated in Figure 8 of the drawings, the groove 12 may be deep and narrow to admit of the saw blade 13 entering the same edgewise. Reinforcing strips 14: are secured to opposite sides of the longitudinal member 10 and project a short distance beyond the end member 11. Short bars 15 are slidable on the end members 11 between the projecting ends of the reinforcing strips'll. Loops 16 secured to the inner ends ofthe bars 15 embrace the end members 11, and retain theV of the saw blade 13 which are attached thereto in any determinate way. One of the stems 17 is threaded and receives a tail nut 18 whereby the stem may be adjusted longi-` tudinally to tension the saw blade 13, or relax the tension thereon,.as required when moving the saw into operative position for use or adjusting it into inoperative position lto be out of the way whennot required for service. When .the saw blade 13 is relieved of tension the bars 15' may be moved outward or inward.y When the saw blade 13 is under tension the bars l5 are held in either' extreme. position substantially as indicated in Figures 1 and 2 of the drawings.

The construction illustrated admits of the frame comprising bars of wood which are strengthened and reinforced by means of the strips 14 and angle irons 19 disposed in the angles formed between the members 11 and 10. Braces 2() are interposed between the members 10 and 11 and are channeled in their outer sides to receive members 21 which constitute legs or branches of a compass or scribe. The legs or members 21 are pivoted at their inner ends to the braces 20 and their outer f member 10.

be readily understood. A knob 24. at the outer side of each of the members 21 provides convenient means for withdrawing the members from the channel of the braces when adjusting the tool for use as a compass or scribe.

A chuck 25 is provided upon the outer side of the outer end of one o1 the members 11 and is adapted to receive a boring tool such as an auger 26. A knob 27 is provided at the outer end of the opposite member 11 to be grasped when the tool is adapted for use as a brace for boring when a tool, as 26, is litted to the chuck 2. A convenient grip is provided midway the ends oit the longitudinal rlhis grip consists of an inner sleeve 27 and an outer sleeve 28. Luge 29 project outwardly ifi-oni the reinforcing strips 1d; and the sleeves 2"? and are disposed therebetween' to be maintained in a given position. The inner sleeve 27 is :formed in a side with a longitudinal opening 29 to register with the groove 12, whereby provision is had for entry and exit of the saw blade 1.3.

-with the groove 12, whereby the saw blade 13 may enter or leave the groove 12. It will thus be understood that the sleeves 27 and 28 besides forming a lgrip provide retaining means for holding the saw blade'l within the groove 12.

l/Vhen the tool is adapted for boring openings the members 21 are folded within the channels of the braces 20 and the saw blade 13 is adjusted to be housed within the groove 12. An auger 2G, or other boring tool, is

The outer sleeve 28 is likewise termedV lin a side with an opening 3() for a nue purfitted to the chuclr 25, thereby adapting the tool for use as a hand b `ace, as will be readily comprehended. To adapt the tool for use as a saw the boring tool 26 is removed, and

the elements 27 and 28 comprising the grip f Vadjusted to bring the openings 29 and 30 in register with thegroove 12 to admit oit moving the bars 15 outwardly into the position indicated in Figure 1 of the drawings. lVhen the saw blade istensioned the bars 15 are retained in the extreme positions indicated in Figure l oit' the drawings. TWhen the tool is desired for use as a compass or .scribe the saw is adjusted `so as to be out of the way and the men'ibers 21 are moved into the required position and are held -in the located position by retightenii'ig the clamp screws L3 which were previously loosened to admit of adjustment of the members 21.

Having thus described the invention, I claim: i

Acomnound tool comprising a substantially U-shaped frame, channel braces connecting the longitudinal and end members of the frame7 members adapted to be housed within the channel braces and pivoted at their inner ends thereto, means for securing the pivoted members to the braces in adjusted position, reinforcing strips applied to opposite sides of the longitudinal member of the iframe and projecting beyond the end members to embrace the sides of bars, there being a groove in the back of the frame, bars slidable on the end bars of the frame, a saw blade connected to the ends of the sliding bars and adapted to be housed within the grooved back of the frame, concentric sleeves embracing the longitudinal-member of the frame and the reinforcing strips at the .sides thereof and provided with openings in their sides to register with the Oroove in the back of the frame9 and means for holding the inner sleeve against rotation.

In testimony whereoi I arllix my signature.
